Sunnen Products Company (St. Louis, MO) recently completed an order for several honing machines from Jasper Engines & Transmissions (Jasper, IN), including the SV-20 and SH-4000 models, as well as necessary tooling and abrasives. Jasper now has a total of seven SV-20 engine-block honing machines at its plants in Jasper and Crawford County, IN, and Willow Springs, MO. The company is also using the new SH-4000 horizontal honing machine for honing turbocharger housings, a new and growing segment of the business.
Jasper is the largest mass remanufacturer of a diverse line of drivetrain components in the U.S., producing almost 150,000 gas and diesel engines, transmissions, differentials and rear axle assemblies annually. The company is owned by its more than 2,000 associates and has dozens of locations across the U.S.Their products also include diesel fuel and air components, along with stern drives, outboard lower units and power heads.
Sunnen has sold more than 80 SV-20 honing machines since the product’s release in 2013, after a development program that included strong input from Jasper. “We developed this machine for production engine remanufacturers, custom engine builders and race teams, so it includes a wish-list of features that’s a hit with this market, thanks to suggestions provided by the Jasper team,” said Bob Dolder, the automotive sales and application manager for Sunnen. “The SV-20’s pure vertical stroke, combined with high spindle power and the 8-stone diamond tool, produces bore roundness, straightness, shape and form that are as good as factory original – and it’s quick. Machines with the rocker-type stroker do a commendable job, but they cannot match the cylindricity produced by the SV-20. Moreover, the programmability of the SV-20 gives Jasper more flexibility in assigning operators because the machine retains the “recipes” for all the different blocks, minimizing the need for operator input. Spindle reversal is another new feature on these machines. This also enhances bore roundness and surface finish, and helps keep the honing stones dressed.”
Sunnen is one of the world’s largest vertically integrated manufacturers of honing systems for precision bore sizing and finishing. Its core technical competencies include R&D and manufacturing of honing systems, tooling, abrasives, lubricants and gaging, along with high-production turnkey system integration. The company employs more than 650 people at offices and factories around the world.
